How American Mah Jongg Works—from Absolute Zero

You do not need to know a single Mah Jongg word before starting this lesson. We will begin with the physical objects, explain what each one does, and introduce the game’s vocabulary only after the underlying idea is clear.

First, what is on the table?

American Mah Jongg uses small decorated pieces called tiles. Tiles do much the same job that playing cards do in a card game: each one has an identity, players collect them, and particular combinations matter.

Four people normally play. Each person has a rack, which is a small stand that holds her tiles upright. The decorated faces point toward the player, so the other players usually cannot see them.

The group also uses an annual card. This is a printed menu of the exact tile combinations that can win during that year. Experienced players keep looking at the card throughout the game. It is not something you are expected to memorize.

Finally, rows of face-down tiles sit in the center of the table. These rows are called the walls. Players take new tiles from them as the game continues.

What does “your hand” mean?

The tiles you currently have are often called your hand, even though they are sitting on your rack.

You may also hear someone call a winning combination on the annual card “a hand.” The same word is used in two related ways:

• Your hand: the tiles you currently possess.
• A hand on the card: one exact combination you could try to complete.

If that feels confusing, use “my tiles” and “a combination on the card” for now. Those phrases are perfectly clear.

What are you trying to do?

You are trying to make your tiles exactly match one winning combination printed on the current annual card.

Most winning combinations contain 14 tiles. They may require particular numbers, matching tiles, flowers, winds, or dragons. You do not need to understand those families yet. The next lesson will show them to you.

Think of the card as a menu. You choose one possible combination to work toward, but you may change your mind as different tiles arrive.

What happens during an ordinary turn?

Set aside the special rules for a moment. An ordinary turn has three actions:

1. Take one face-down tile from the wall. Players call this drawing a tile.
2. Look at all your tiles. Decide whether the new tile helps you move toward a combination on the card.
3. Place one tile you do not want face-up in the middle and say its name. Players call this discarding a tile.

After you put down one unwanted tile, the next person normally takes a turn.

Everyday version: take one, think, put one down. Game-table version: draw, evaluate, discard.

Why must you say the discarded tile’s name?

The other players need to know what you placed in the middle. Saying “Five Dot,” “North,” or another tile name makes the action clear, especially when someone cannot see the tile easily.

You will learn those names gradually. At a beginner-friendly table, it is reasonable to ask, “What is this tile called?” before you put it down.

What does “claiming a discard” mean?

Sometimes, another player is allowed to use the tile you just placed in the middle. Taking that tile is called claiming or calling the discard.

This is an exception to the ordinary turn rhythm. It follows specific rules, so you do not need to decide when it is allowed yet. For this lesson, simply know why someone may suddenly say a tile’s name and reach toward the middle.

We cover the actual requirements in Calling Tiles and Exposures, after the basic table makes sense.

What happens before ordinary turns?

American Mah Jongg begins with setup and a tile-passing activity called the Charleston. Players pass small groups of tiles to one another before taking normal turns.

The Charleston matters, but it is not necessary for understanding the goal. Learn the table and the ordinary turn first. Then the passing sequence will have something to attach to.

How does someone win?

A player wins when her tiles exactly match a valid 14-tile combination on the current card. She declares Mah Jongg so the table knows the game has ended.

For now, keep only this mental picture:

1. Four players each hold tiles on a rack.
2. The annual card shows the combinations that can win.
3. On an ordinary turn, take one tile and put one unwanted tile down.
4. Continue shaping your tiles toward one combination on the card.

That is the game’s backbone. Everything else is a detail attached to it.

A one-minute check

Without using the formal vocabulary, explain an ordinary turn aloud:

“I take one new tile, decide whether it helps, and place one unwanted tile face-up in the middle.”

If you can say that, you understood this lesson. Next, meet the tile families so the decorated pieces stop looking like 152 unrelated objects.
